For loop counting between numbers

What is the problem with the code? It always return me the B value. I'm trying to count the numbers between two values. Thanks in advance!

 #include <stdio.h>
 #include <stdlib.h>
 int main(void) {

      int a, b, i, cont;

      printf("Digite um valor de Inicio: ");
      scanf("%d", &a);

       printf("Digite um valor de Fim: ");
       scanf("%d", &b);


       printf("Existem %d numeros entre os valores fornecidos", i);

    return 0;

    Need to update cont when for loop execute i.e calculate numbers between two values. And then print the cont. Easy way: use b - a equation instead of loop.

    In C the following is the syntax of for loop.

    for ( init expression; condition expression; update expression) {

    Note that, you can have multiple statements separated by , in each expression of the for loop.

    To answer your question, you need to do,

    for ( <initialize i with zero, initialize count to zero>; 
          <check to break the loop, it is already correct>; 
          <increment i, increment count>);

    Set the counter:

    if(!a < b){
        printf("Numbers should be not equal");
    int count=0;
    for(int i=a;i<b;i++)
